Lapping Machine DX75480 has to be used for reconditioning
the
ball seat internal valve cone on the common rail Bosch type
injectors
Lapping Machine DX75480
Lapping Machine DX75480 is equipped with spindles, which tips
have a different conical shape in order to adapt to the different
valve seats to be grinded. The choice of the right conical angle
allows precision grinding on the right spot of the cone damaged by
the small ball hitting action.
The grinding operation has to be done using the small grinding
paper strips, which should be positioned between the spindle and
the valve seat (on top of the valve seat). The grinding strips are
of different grinding action, from the raw one to the very fine one
for end-lapping and are of the right size to suite the valve
seat.
This ginding/lapping machine has to be used fore reconditioning
the ball seat internal valve cone on the common rail Bosch type
injectors, in order to re-establish the ball tightness in her
seat.

(how to use available on codec.ditex.it)
The spindles cones are made considering the thickness of the
abrasive paper. Pay attention, the use of not compatible abrasive
papers can damage the valve cone.
The use of the grinding/lapping stripes offers the following
advantages: • The grinding surface of the strip exhausts after e
few seconds, avoiding eventual seat damages in case of too strong
or to long pushing. • The conical tip of the spindle is not in
contact with grinding
material and therefore it does not wear off.
*INDISPENSABLE MICROSCOPE DX75680
RECOMMENDED MICROSCOPE LIGHT DX75681
First check ball valve seat condition with the microscope* On
the picture you may see an example of a valve seat with signs of
wearing. Without Lapping Machine DX75480 this valve SHOULD BE
SCRAPPED.
